Pre-authentication memory corruption via openvpn_push1 overflow
Published Nov 22, 2022 · Updated Apr 29, 2025
Buffer overflow in NETGEAR R7000P firmware 1.3.1.64 allows remote attackers to corrupt memory through the openvpn_push1 parameter. The firmware's OpenVPN configuration handling writes an oversized parameter value beyond its destination buffer, although public records do not identify the responsible function or buffer. The vendor identifies the flaw as reachable before authentication but does not document whether successful exploitation causes a crash or code execution.
